64165805 ÷ 210 
Our goal is to divide 64165805 by 210.

Going ahead to step 1:
210 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 210

Advancing to step 2:
210 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 64, we end up with 64.
Append the next digit (1) from the dividend to 64 and continue with: 641 / 210

Advancing to step 3:
If we divide 641 by 210, we get 3 and a remainder of 11.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 630 from 641, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 210

Step 4:
When dividing 116 by 210, we get 0 with a remainder of 116.
Use 0 as the next digit of our solution. 
Result so far: 30.0
The remainder is 116 after subtracting 0 from 116.
Include the next digit (5) from the dividend after 116, then repeat: 1165 / 210

Going ahead to step 5:
210 goes into 1165 5 times with a remainder of 115.
Use 5 as the next digit of our solution. 
Result so far: 305.0
If we subtract 1050 from 1165, we get 115.
Take the next digit (8) from the dividend and append it to 115, then repeat: 1158 / 210

Going ahead to step 6:
When dividing 1158 by 210, we get 5 with a remainder of 108.
The next digit of our result is 5. 
Result so far: 3055.0
If we take 1050 away from 1158, we end up with 108.
Append the next digit (0) from the dividend to 108 and continue with: 1080 / 210

Advancing to step 7:
1080 divided by 210 is 5 with a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 30555.0
If we subtract 1050 from 1080, we get 30.
Bring next digit (5) of the dividend behind the 30 and repeat the process: 305 / 210

On to step 8:
The number 210 fits into 305 1 times, leaving a remainder of 95.
The number 1 becomes the next digit in our result. 
Result so far: 305551.0
Subtracting 210 from 305 leaves us with 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Advancing to step 9:
210 goes into 950 4 times with a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 305551.4
Subtract 840 from 950 to get 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Advancing to step 10:
When dividing 1100 by 210, we get 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 305551.45
If we take 1050 away from 1100, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 11:
The number 210 fits into 500 2 times, leaving a remainder of 80.
The number 2 becomes the next digit in our result. 
Result so far: 305551.452
Subtract 420 from 500 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 12:
210 goes into 800 3 times with a remainder of 170.
Use 3 as the next digit of our solution. 
Result so far: 305551.4523
Subtracting 630 from 800 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

Step 13:
If we divide 1700 by 210, we get 8 and a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 305551.45238
Subtract 1680 from 1700 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 14:
210 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 305551.45238
Deduct 0 from 200 and we're left with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 15:
2000 divided by 210 is 9 with a remainder of 110.
Use 9 as the next digit of our solution. 
Result so far: 305551.4523809
Deduct 1890 from 2000 and we're left with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Going ahead to step 16:
210 goes into 1100 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 305551.45238095
The remainder is 50 after subtracting 1050 from 1100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 305551.45238095 with a balance of 5e-08.
